Abstract

Arabian coffee, Coffea arabica L., is grown in Kenya at altitudes ranging from approximately 1050 m (3400 ft) to 2200 m (7200 ft). At the higher altitudes the coffee is grown under shade trees; at the lower altitudes it is unshaded. In one of the higher altitude districts, Upper Kiambu, Epigynopteryx stictigramma (Hmps.) has recently become a minor pest. The caterpillar feeds on leaves and may attack berries and flower buds. Outbreaks have occurred on several estates during the past few years and appear to be associated with frequent parathion sprays. The use of this insecticide became general in the district about 1959.
